About Sandvik 046 976 77 PISTON ring
A critical hydraulic component in the Sandvik LH514 percussion mechanism, this piston converts hydraulic pressure into the powerful impact force needed for rock breaking. Located in the BRAKE ASSEMBLY, worn pistons cause reduced penetration rate, increased energy consumption, and decreased overall drilling efficiency.
This is an OEM-compatible aftermarket replacement part for the Sandvik LH514 (LH514). Also compatible with Tamrock branded equipment of the same model series. BK Drilling supplies this part with fast worldwide shipping and competitive pricing.
Frequently asked questions
